This is an example of an aspect of Breivikite ideology in the Daily Mail:

Most of us may not realise this but the ideological Left certainly does, for it has long been part of its grand plan to destroy Western civilisation from within. The plan's prime instigator was the influential German Marxist thinker ('the father of the New Left') Herbert Marcuse. A Jewish academic who fled Germany for the US in the Thirties, he became the darling of the Sixties and Seventies 'radical chic' set.

He deliberately set out to dismantle every last pillar of society – tradition, hierarchy, order – and key to victory, he argued, would be a Leftist takeover of the language, including 'the withdrawal of toleration of speech and assembly from groups and movements which promote aggressive policies, armament, chauvinism, discrimination on the grounds of race and religion, or which oppose the extension of public services, social security, medical care etc'.

In other words, those of us who believe in smaller government or other 'Right-wing' heresies should be for ever silenced.

I recently finished writing a chapter on Anders Breivik's manifesto, '2083: A European Declaration of Independence'. It is a document that is notable for many things, among them its extensive plagiarism, copypasta, and sprawling, barely structured polemics on a bewildering variety of subjects. It draws together a number of elements in contemporary reaction into a prospectus for a very contemporary fascism. The core of it is a fabulation concerning attempt by "cultural Marxists", whose influence extends from Gramsci and Lukacs to Marcuse and Adorno, through 'deconstruction' and 'political correctness', to take control of culture, thought and language and thus 'silence' conservatives and patriots. This theory is what mandates the war against "category A and B traitors". Now, this is not typical mainstream media fare, albeit the gripes about political correctness and left-wing domination of culture are commonplace. As far as I know, Delingpole is the first to bring this Breivikite conspiracy theory right from the margins into the mainstream press - not long after the blood has dried in Utoya, at that.
